NOTE
By common practice and standards definition, television resolution is the ability of
the system to produce an alternate black and white line structure. Each line, black
or white, is counted (as opposed to the common "line-pair" terminology of
photography). Specifications of tv lines are related to the vertical dimension of the
aspect ratio (ratio of horizontal size to vertical size).
The test pattern for resolution is generated electronically as a square wave,
providing alternate black and white images in the display. Generally, the bursts are
calibrated in 100 line increments, in ascending order, as shown in figure 6-23.
Alternate adjustments provide bursts of resolution at any one selected resolution
rate, or a continuous presentation of the desired rate over the entire active raster
as shown in figure 6-25.
